*Says grid collapse caused by fire incident on Kanji/Jebba 330kV line 2
Following the collapse of the power grid that occured in the early hours of yesterday, which caused nationwide blackout, with adverse impacts on homes and businesses, the
It was gathered that TCN engineers had gone to work to restore normalcy when the incident happened, including first restoring about 35mw, and then ramped it up to 193mw and then 273mw before their efforts suffered a setback, resulting in another failure.
The government-owned TCN in a statement signed by its General Manager, Public Affairs,
Mbah stated, "The TCN hereby notes that grid restoration nationwide is in progress and has reached advanced stages with power supply now available in the West, North Central, South, East, and a large portion of the Northern parts of the country. "The power supply restoration is sequel to the total grid collapse, which occurred at about
"In the course of the grid restoration, the process initially suffered a setback; this does not amount to another collapse. In the course of any grid restoration process, challenges may be encountered. This happened today while the grid restoration was in progress, but it was promptly addressed." According to Mbah, the last total system collapse recorded was on
Mbah, added that TCN had been able to maintain 400 days of grid stability because it developed and deployed in-house stop-gap measures and tools that it had continued to use to manage the nations grid and ensuring its stability. "The incident notwithstanding, TCN is determined to continue to do its best to ensure grid stability.
"Meanwhile, the collapse that occurred after a fire incident on Kanji/Jebba 330kV line 2 is being investigated, with the view to forestalling future occurrence and invariably further strengthen the grid", the TCN spokesperson noted. The national electricity grid had collapsed in the wee hours of yesterday, the first of such collapse in the administration of President
This happened while the nation's Minister of Power, Mr.
Some of the Discos alerted their customers about the development and its implication on supply to them. THISDAY gathered that as of 7:a.m. on Thursday morning, the TCN failed to transmit power to the 11 Discos as power grid dropped from 4,355.2MW on
As a result of the development, electricity generation from all the generating plants dropped to OMW, including Afam VI (gas/steam), Dadinkowa G.S (hydro), Delta (gas), Geregu (gas), Geregu NIPP (gas),
The national grid system is operated by the TCN from Osogbo in Osun state. Many plants, were affected, including Afam VI, which at some point had just 0.70MW, Dadinkowa with zero mw, Ibom power had 32.90mw, Jebba was still struggling with 240mw while Olorunsogo also suffered zero generation, before finally shutting down.
"EEDC wishes to inform her esteemed customers of a total system collapse which occurred at
Also explaining the situation on his Twitter/X handle, the Minister of Power,
"This led to sharp drops in frequency from 50.29Hz to 49.67 Hz at 0:35:06Hrs with Jebba generation loss of 356.63mw," Adelabu said, adding that Kainji then started dropping load from 451.45 mw at 00:35:07 hours to zero. "At 00:41 hours frequency dropped further from 49.37 Hz to 48.41 Hz resulting in the system collapse of the grid. "We are on top of the situation and speedy restoration is in progress. The fire has been fully arrested and over half of the connections are now up and the rest will be fully restored in no time.
"My sincere appreciation to those who responded or expressed concern via different channels and the team of engineers for their prompt response to the situation and work done so far. Let's get the restoration work completed as soon as possible," he said.
Industry data also showed that the electricity grid recorded about seven collapses in 2022, with the most recent grid collapse occurring on
